I will discuss the limitations of traditional visual galaxy morphology, especially the Hubble-based classification of early-type and spheroidal galaxies. While visual schemes remain historically important, they oversimplify spheroidal systems, rely heavily on subjective criteria, and fail to capture low-contrast structures, embedded components, and variations in concentration. I argue that galaxy morphology must be treated as a quantitative, multidimensional, and continuous problem rather than as a set of discrete visual classes. Morphometry provides this framework by combining structural and non-parametric parameters such as S\u00e9rsic index, effective radius, concentration hierarchy, asymmetry, smoothness, entropy, spirality, and profile curvature. Examples from Morfometryka and ongoing applications to SDSS, DECaLS, JWST, LSST, and environmental studies show that spheroidal galaxies occupy a richer morphometric space than implied by the classical Hubble sequence. The central point is that morphometry is not merely a technical refinement of classification, but a necessary paradigm shift for interpreting galaxy structure and evolution.<\/p>\n","protected":false},"excerpt":{"rendered":"
